Repair Partition Table Android

I have a Xperia L with CM 12 installed successfully.Recently i was poking around with it's partition table using ADB to increase my internal storage and might have done something wrong.Now the phone doesn't start,doesn't go in CWM,doesn't go in fastboot and doesn't connect as an ADB device as well.The phone is detected as a HID complaint device(Don't know what that means) and i have hit a wall repairing this.Any help would be appreciated.Is there some special application for this?Or something else?Do i need to interact directly with Motheroard by opening the phone!There's got to be some way right?
Not losing hopes on this one.
Please help :P
